Delay of Analog TV Shut-off

Last night the Senate passed a bill to delay the shut-off of over-the-air analog TV from February 17 to June 12, 2009. The Obama administration had urged the delay, saying that many consumers are not ready.

Nielsena said last week that more than 6.5 million U.S. households are not prepared and could see their television sets go dark next month.

The House might not immediately pass the Senate’s version of the bill, which does not specify how the costs of a delay would be covered. The House could add its own provisions, which would require further Senate action. It could also waive budget rules and seek funds in the stimulus package. Still, it looks like the House will pass some bill that will delay the shut-off until June 12.

See our previous post on Digital TV Transition to see if you might be affected by this transition. Or go to the government’s National Telecommunications and Information Administration (NTIA) site for more info and your free $40 voucher for a digital TV converter.

UPDATE: Despite the unanimous vote by the US Senate to delay the Feb. 17 deadline to transition to digital television, the changeover will proceed as planned after a vote Wednesday by the House of Representatives.

It is unclear if this permanently kills the delay. With less than three weeks untill the planned analog shut-off, the window is almost over for a delay. The television stations need time to make preparations so unless something else happens this week, I now expect the Feb 17 transition to happen.

UPDATE 2: Today (February 4, 2009) the House of Representatives voted again and this time passed the delay of the analog shut-off until June 12, 2009. Now President Obama will sign the delay into law.

Down & Up Worm Worst Ever

Over the last few months, the “Down and Up” worm, also known as “Conficker” has infected an estimated 6% of all PCs worldwide. The concern is what the authors will now do with all these compromised systems. They could ask for credit card information as the bogus Antivirus 2009 does. They could use the computers to attack and demand money from websites through denial of service (DOS) attacks. No one knows yet what the intentions of the authors are.

It is considered the most professional and pernicious worm attack that researchers have yet seen. It effects all versions of Windows. As a worm, it does not require any user action for the computer to be compromised. The machine must just not be recently patched.

Download the Malicious Software Removal Tool (also available in Windows Updates) in order to protect your computer or to possibly get rid of the worm (most people who have it do not know). Then you can feel comfortable that your computer is owned by you and not by the bad guys.

CNN to create 3D Inauguration Image

If you are going to the inauguration, you can take pictures (under 10MB in size) of the event and send them to themoment@cnn.com.

CNN will then use Microsoft’s PhotoSynth software to create a massive 3D image. It will be interesting to see how well it works, especially since most of the event will be covered with people. Since the people move, it’s not clear how well the software will be able to match images up. But PhotoSynth has created great 3D experiences in other locations.

UPDATE: See the results of CNN’s PhotoSynth project at CNN’s The Moment site.

Presidential Inauguration

The Presidential Inauguration of Barak Obama on January 20th is expected to be a huge event, eclipsing the previous largest ever turnout since Lyndon Johnson’s 1965 inauguration with 1.2 million people. D.C. Mayor Adrian Fenty says up to 4 million people could converge on downtown Washington for the inauguration, although the Secret Service says that it expects 2 million people.

Screenings

Every one of the 240,000 people attending the actual swearing-in ceremony will be screened by walk-through or hand-held metal detectors. Beyond the obvious weapons not allowed, you also will not be allowed to bring:

  • Sticks or poles
  • Pockets or hand tools, such as “Leatherman”
  • Packages
  • Backpacks
  • Large bags
  • Duffel bags
  • Suitcases
  • Thermoses
  • Coolers
  • Strollers
  • Umbrellas
  • Tripods and camera bags
  • Laser pointers
  • Signs
  • Posters
  • Animals (other than service animals)
  • Alcoholic beverages
  • Other items as determined by and at the discretion of the security screener

So while you might have thought it would be funny to point a laser pointer at the presidential motorcade, it will not be allowed.

It is likely to be so crowded that you won’t want to bring much with you besides your cellphone and camera.

Cellphones

Cellular carriers are adding capacity with temporary towers along the parade route. Still, with an unknown number of visitors, there is concern that the network will be overloaded.

One suggestion is to use text messages if your calls are not going through. These take up very little bandwidth and should work more easily.

Emergency responders and 911 calls will be given priority so those calls should be able to get through.

Getting to the event

All N. Va bridges will be closed to cars. You can walk or bike the bridges.

D.C. will be mostly shut down to traffic.

News

The Washington Post has an Inauguration Central website that includes:

  • A live webcam that is focused on the U.S. Capitol to show the construction of the Inaugural stage.
  • An FAQs section that gives users valuable information about ticket availability, transportation, ceremony timing and parade information, providing a sense of what to expect during in the weeks leading up to the Inauguration.
  • A downloadable map of the parade route with the most updated road closures in the area.
  • A calendar of Inaugural parties and events happening during Inauguration Week.
  • Quizzes, polls and discussion threads which give users a chance to test their inaugural knowledge.
  • A visitors guide which includes an interactive map of attractions on The Mall, suggestions on planning a trip to D.C. and advice on where to get lunch post-inauguration.
  • A section that features inauguration history, including a slideshow that provides a look at past inaugurations.

Inauguration Pop-up

One of favorite items to commemorate the inauguration is a pop-up picture of the event that you can print out and make yourself. This low-tech print out might not be like attending the real thing, but it will certainly be more comfortable.

Delay to Digital TV Transition?

The incoming Obama team has written Congress asking for a delay of the planned February 17th turn off of analog over-the-air TV signals. While most people won’t notice this eventual transition, there are some hurdles.

Most People Aren’t Affected

The loss of analog over-the-air signals will not affect most people who use one of 1) cable, 2) Satellite (Dish or DirecTV), 3) digital over-the-air (still using an antenna), or 4) fiber (FIOS TV service). Most people in the D.C. area will not be affected. TVs made in the last couple of years should have digital tuners, known as ATSC tuners.

Expected Problems

In my experience setting up home theaters and TVs in the DC metro area, I have found some problems that will likely come with this transition:

  1. Analog signals travel better. While the term “digital” seems like it should mean “better”, it has a big downside. Analog tuners deal with missing data (the result of a poor signal) much better. Digital signals that do not have enough data quickly turn to jaggies and then a blank screen. This is sometimes referred to as a digital cliff effect. The same concept applies to HD Radio. Digital therefore does not travel as far as analog and it does not work as well through walls. Even in Arlington, Virginia, not far from the TV towers, a good signal usually requires an antenna to be placed in a window, on the roof, or in a high attic. People farther away will have more problems. Residents in rural Virginia might now be too far to get any over-the-air signal.
  2. Old homes in D.C., Virginia, and Maryland can not be easily wired for cable. The house walls might be made of concrete, brick, or stone that is difficult to wire through. This has caused some local residents to opt for analog over-the-air TV instead of cable or FIOS. Other people have decided to only wire their living room, and still use analog over-the-air in other rooms. The old construction can also cause problems running an antenna to a window, roof, or attic.

Possible Delay

The Obama team has requested a delay because the National Telecommunications and Information Administration (NTIA), which is to provide education and $40 vouchers for people to buy digital TV converter boxes, ran out of money on January 4. There is also concern that many people, especially poorer and more rural areas, have not yet heard that they will need a converter and a larger antenna.

Web Resources

To find out what kind of signal you can expect and what kind of antenna you need to get digital programs, see AntennaWeb site and click Choose an antenna. Another useful site is HDTV Hub, which lists many users experiences for their particular locations. You can find out through these sites what kind of over-the-air HDTV experience that you can expect.
